Answer:
720 mi²
Explanation:
The map has a scale of 1 in: 30 mi, meaning that for every inch you see on the map, in the real-life location, it will measure 30 miles. So we can find the area of the park on the map and then turn it into miles using the scale:
Area of a rectangle:

Replace the known values:
![A=(4)(6)\\ A=24](https://img.qammunity.org/2022/formulas/mathematics/college/l9c1srlg3b7swyes2f5on9vuv8jagy38j9.png)
The area on the map is 24 mi², we can turn it to miles using the scale by multiplying our result with 30:
![A=(24)(30)\\ A=720](https://img.qammunity.org/2022/formulas/mathematics/college/ryxcaug38r3c2vthwc433bafc3co3sngsv.png)
And last but not least, don't forget to put the unit!
